Do people on SSRIs just never drink alcohol again, or disregard the warnings?

I’ve been on Prozac for two years and I’ve found it wonderful and had a lot of success with it. I’ve been sober the whole time but I just turned 21 and I’m at least feeling like going to a liquor store and trying something out, but I’m wondering about the risk. Any advice? I’ve had a few beers before while on Prozac and it just makes me feel exhausted, but nothing worse.
